An unmistakable haze has been hanging in the air recently as smoke from the raging wildfires in B.C. wafts over the border into Alberta. Although conditions have cleared a bit since this photo was taken on Wednesday, July 19, residents in the region — especially those with respiratory conditions such as asthma or COPD — are encouraged to keep an eye on the provincial status of the Air Quality Health Index and to avoid strenuous physical activities outdoors when the forecast remains high. http://www.environment.alberta.ca/apps/aqhi/aqhi.aspx▲
